SEPTIC Application led August 5,

To all whom 'it may concern."

Be it known that I, AHENRY C. R'oGERs,a

subject of the King of Great Britain, residing .at Estes Park, in thecountyq of Larimer-and State of Colorado, have invented new and useful Improvements in Septic fTanks, of which the following is a specification.

- This invention relates to apparatus designed for the purpose of catalyzing sewage and one ofthe principal objects of the invention is to provide a tank having various partitions and a system of pipes whereby the lighter and heavier constituents of the sewage may be separated, dissolved and deodorized by oxidation.

Another object of the invention is to provide a tank in which the inlet pipe is placed in communication with the outer air in such away that the noxious gases from the tank cannot enter the sewer or house drain.

These and other objects may be attained by the construction illustrated by the ac companying drawing, in whicht* Figure l is a plan of the tank Withthe cover or top removed, Fig. 2 is a vertical longitudinal section of the same with the cover and manholes in place.

Referring tothe i.li'awing, the numeral 1 designates a tank constructed of masonry or concrete walls, a concrete bottom and a top 4, preferably formed of concrete and provided with suitable manholes 5 and 6. 'l`he inlet sewer pipe 7 enters thc .tank through a depending pi ie 8 which terminates at va point below-thc level of the surface of th'e sewage in the tank. A Ventilating )ipe 9 is attached to the pipe 8 and extended tlirough the top 4, the upper end of said pipe having a perforated grating through which only fresh air can enter and ventilate the sewer. A partition 11 is formed in the compartment 1, and at the 'bottoni of said. partition a perforated screen 12 is secured, said screen preventing coarser particles of sewage lroir passing into A stand pipe 13 is disposed in compartment l, said pipe being connected tothe outlet pipe 14. -A partition 15 of less height than partition 11 separates the compartment 1'LL from the third compartment 1l. in this compartment an oxidizing device located, comprising the vertical pipe 16 connected by the tee 17 to the outlet pipe 14, said pipe 16 being' surspeciination of Letters Patent.

water seal for preventing the sewage gas from entering the sewer or house drain 'but at the same time admitting fresh air to the saine. After the sewage passes into the compartnient 1 the lighter constituents will be retained while that portion of the heavier which can. pass the screen 12 will move to compartments lu of the sewage in the coinpartnient 1L the heavier constituents will bel arrested by the partition l5 whereas the i lighter can pass over said partition into compai'tiiient 1h, the heavier' or more dense con Astituents in compartment 1b will descend and, by displacement, will be forced to rise into the sleeve pipe 18until it passes into the pipe 16A throng i the small holes near its top.

This pipe 16 being in direct communication with the ou'tside air the effluent, or matter discharged, becomes oxidized. 'lf the circulation of air about the pi e 18 is sluggish a forced draft can be in( uced by artificial means such as by a spray of water. If the discharge from the tank is more than normal the sew age will rise till it flows over the to of the pipe 16, when the tendency to rise W' l be arrested.- Tlie tank can be drained of its liquid contents by removing the pipesV 13, 16 and 18 whenever required.

l claim:

l. A septic tank comprising a series of' ing which the compartment can be drain'ed;'

an oxidizing device in another compartment comprising a pipe extending to a point near the top of the tank, and a sleeve surrounding said pipe and leading to the outer air.

2. A septic tank provided with a series of partitions dividing the tank into separate compartments, an inlet sewer pipe in one of said compartments, said inlet pipe having a depending connection forming a water seal,

a connection extending through the top tok ventilate the sewer and house drain, one of said partitions being provided with a screen ipe, an outlet pipe connected thereto,` an oxidizing device in a separate compartment, said oxidizing device i In testimony whereof I'eix my signature eomprisng a .pip oonneetpd to the outlet in presence of two Witneses. 4 pipe an `rovlde with per oretlons Hear 1ts upper eng, a sleeve surroundmgsaid plpe, HENRYC ROGERS' 5 said sleeve leading to the outer air end pro- Witnesses: l
